1

Does VTP support having multiple VTP servers in a domain?

yes

2

In a VTP domain that is version 3 what must the primary VTP server be set to?

VTP primary

3

What does VTP use in order to advertise updates across trunk links to all switches in a VTP domain?

multicast address

4

What are the three types of VTP advertisements?

summary, subset, client requests

5

When does a VTP summary advertisement occur?

every 300 seconds or when a VLAN is added, removed or changed

6

When does a VTP subset advertisement occur?

after a VLAN configuration change occurs

7

When does VTP client request advertisement occur?

when a switch with a lower revision number joins a VTP domain that has a higher revision number

8

Should you reset every switch to a VTP revision number 1 or 0 before connecting it to a VTP domain?=

0

9

What happens to access ports when you remove a VLAN from a switch?

access ports are move to VLAN 1

10

Dynamic Trunk ports are established by switch ports sending what to negotiate whether the other end can be a trunk port.

DTP advertised packets

11

How often does DTP advertise itself to neighbors so that they are aware of it DTP status?

30 seconds

12

Ethernet network speeds are based on the powers of what?

10

10Mbps, 100Mpbs, 1Gbps ...

13

What's another name for a logical EtherChannel?

member interfaces

14

Does STP operate on a logical link or a physical link?

logical link

15

What is the primary advantage of using port channels-EtherChannel?

reduction in topology changes when member link goes down.

16

What does DWDM stand for?

What bandwidth are DWDM transceivers capability of?

Cisco Dense Wave Division Multiplexing

10-Gigabits

17

What are the port modes for PAgP - Port Aggregation Protocol?

Auto and Desirable

18

What are the port modes for LACP - Link Aggregation Protocol?

Passive and Active

19

What is LACP fast?

LACP is advertised every 1 second and links can be identified and removed in 3 seconds compared to 90 seconds.

20

Maximum number of port-channel interfaces need to be configured only on what?

For best practice and to accommodate load-balancing hashes, maximum number of port-channel interfaces should be configured in powers of?

master switch

two (ex. 2, 4, 8, 16)

21

The port-channel master switch control what, and how?

which member interfaces and associated links are active by the LACP port priority

22

What does the LACP system priority identify?

which is the master switch for a port channel

23

What is the master switch on a port channel responsible for choosing?

which member interfaces are active in a port channel

24

The traffic that flows across a port-channel is forwarded out member links based on what type of calculation?

calculated hash values across various packet header fields
